(1) What's the purpose of specifying the params if it is going to figure it out on its own? (2) What happens when I specify a different number of params than what is in the query string?(3 params in query, but 4 specified, or 2 params in query, but 1 specified.) (2) How do I specify something like this:1. Param 1 is an int.2. Param 2 is unknown - figure it out.3. Param 3 is a varchar. Does it even make sense to specify something like that? If these questions are answered by a discussion thread from a while back, I'd appreciate pointers. Thanks for your time Tom and others, I'm enjoying this and remembering C all at the same time. -- Jonathan Gardner jgardner@jonathangardner.net
